LASTING-MACHINE.

Application niet! December To all whom t may cof/wem:

it known that l, Ninnmri THOMAS 'coirrnorniir Renners, a subject of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes, and more particularly to lasting and nailing machines of the type known as hand method lasting machines, although Some features of the invention are capable of use in fasteninginserting machines in which no lasting elements are included.

The present invention has particular reference to lasting machines of the hand method type which employ instrumentalities for inserting after each pulling operation of the pincer a plurality of tacks, or

other loose fastenings, into the overworked shoe materials to hold the same in lasted po sition. A machine employing a single pincer which is caused to operate for lasting successive portions of the upper, and in connection with which type of machine the present invention will he explained, is shown in U. S. Letters Patent No, 584,744; and a Vmachine of this same type which is equipped with mechanism for inserting a plurality of fastenings along the edge of the shoe at each pulling operation of the rpincer, and means for rendering one or more of the devices for inserting said fastenings inoperative, is shown in U. S. Letters Patent No. l,007,05l.

One of the objects ofthe present invention is to increase the capacity of the machine shown in the last-namedpatent and to adapt it for operation upon a greater varietyof Work. To this end an important feature'of the invention consists in means for inserting, at each cycle of the machine, a plurality of either of a plurality of kinds of fastenings to secure a lasted shoe upper in position and lmeans to control the insertion of either a plurality of one kind of fastening, a plurality of another kind, ora different number of either kind of fastenino.

hopper through the raceways to a tack block,

or similar device, from' which they are driven into the Work or are transferred to an adgacent fastening inserting position,

and suitable tack, or other fastening separators, are employed to separate each individual fastening from the others in the raceivays and permit it to pass to the openings of the tack block. Another feature of the present invention consists in improved fastening separating mechanism constructed and arranged toeffect separation of the individual fastenings at a locality remote from the tack block or other device to which the fastenings are passed for insertion into the Work, or are transferred to an adjacent fastening inserting position. This arrange ment has been found to permit of the provision'kof a plurality of fastening supply means, such as hoppers, raceways, and separators without involving undue complications of the working parts,y and Without necessitating the employment of small, re1- atively Weak and easily deranged Working parts, or reducing the speed at which the cyclesofoperation of the machines can be repeated. e

Another important feature of the present invention consists in a plurality of means for determining the separation of the fastenings from the sources of supply, together with a single operating member which is adjustable, automatically or manually, for1 actuating at any one operation a selected number onlv of the separating means.

Another feature of the invention consists in means by which the singlel operating member is automatically actuated through connections with the mechanism which controls the making of plaits in the upper, when lasting around the toe to take care of the fullness at that point. When the plaiting mechanism is in operation said member Will be so positioned as to effect the actuation of one separating means or separator controlling one raceway which contains, for example, long tacks so that one long tack will be inserted in the Work following each pulling operation; when the plaiting mechanism is rendered inoperative, the member hereinhefore mentioned will be moved to a different position where it will effect the simultaneous operation of two separators which control the feeding of two long tacks, which tacks will be driven into the work following each pulling operation. Another feature of the invention consists in means operated from the usual bunter or edge gage employed in this type of machine for causing the member to assume still a different position, where it will simultaneously actuate two fastening; separators that control the feeding' of fastenings of a different kind, for example, short tacks, which are conducted from the tack hopper by two other raceways. The last-named position of the adjustable actuating member for the separators is suitable during the time .that the lasting operation is taking place along the sides of the shoe, and at the shank portions thereof. The hunter or edge rest being at such time pushed back from the forward position which it ordinarily occupies while the lasting operation is taking place about the heel and toe portions of the shoe.

Another enure of the invention consists in means for manually adjusting the member which is automatically adjusted to different positions for controlling the supply of either one, or a plurality of long' tacks, so as o effect, in addition to the above-desc )ed functions of such member, the supply of one, or a plurality of short tacks. By this construction, therefore, the machine may b e caused to drive one, or a plurality of lone; fastenings at each cycle of its operation, or one, or a plurality of short fastenings at each cycle of its operation. This construction. will be found particularly advantageous in those classes of work wherein it is desirable to form plaits in the upper at the shank or along the sides of the shoe, and to drive a single short fastening to secure each overworked plaited portion in position, instead of the two short fastenings which are ordinarily driven when lasting these portions of a shoe without forming plaitsin the upper.

These, and other features of the invention, including important details of construction and combination of parts, will be more fully described hereinafter, and the novel features will be particularly pointed out in the appended claims.

T he machine comprises a column 100 upon which is supported a head ad() which carries bearings for the usual cam shaft. This shaft is provided with the usual cams for actuating the pincers 500, including the updraw cam connected yieldingly to the updraw lever from the front end of which the pincers 500 are suspended; the closing cam, which operates through the usual rock shaft carried on the updraw lever for shutting the jaws upon the upper andi holding them closed while the pincers are lifted to stretch the upper; and the overdraw cam which is actuated for moving the pincers inwardly over the edge of the shoe bottom to carry the pulled upper into position to be fastened.

he machine is also provided with the usual, or any desirable mechanism for imparting the necessary movements to the pincers 500 for forming plaits in the upper at those por( tions of the shoe where the fullness of the leather demands plaits, as, for instance, at the toe, or when desired along` the sides of the shoe. The plaiting mechanism may be controlled by devices which A from the usual knee lever h lever may be supportedfrom the y6 shown in section in Fig. 2. flfhese ai parts are old and well known, and are shown and described, for example, in the drawings and specification of U. S. Letters Patent No. '5S-Jail above referred to, and 'to which reference may be had for a more full understandingr thereof.

The shoe materials which are worked into lasted position by the pincers are secured in such position upon the shoe bottom by fastenings, such as tar-ks, which may he driven from the usual tack block 40 by drivers 200 am le the mechanism referred to in )rior U. S. Le'tersy `latents Nos. 584,744 and 1,007,051. The tacks are carried in a hopper l,` which may be divided into two compartrespectively, to receive long 't i7' tacks. From the compartments the raceways 2, 3, il and 5 are Supplied. the rz-rcr-nva ys 2 and for example,

being adapted to receive long tacks and the raceways 4 and 5 short tacks. Each pair of raceways has a detachable cover, one o1 which, 7, is shown in F ig. 2, said covers acting to retain the tacks in the raceways. Flach raceway is provided with a reciprocating notched separator 3, see Figs. 3, 4 and 5, which is guided 'tor reciprocating movements across the ends of the raceways, and each separator is connected by a trans' verse bar with one of four studs 8, 9, 10 and 11, which project, respectively, from the bars 13, 14. and 15. said bars being guided ior re;V arocating movements in openings :formed in brackets 17, 18, which project rigidly from a portion ot the machine frame. 'Ehe ends of the raceways and the separators are covered by detachable covers 19, 20, 21 and 22 which are secured in position thereon by screws, or other suitable Jenings.

A plate 23, provided with an'opening 24 opposite each raceway, is arranged to be re-v ciprocated across the ends of the raceways, and to pass between each separated tack and the next one in the raceway and insure that the separated tack remains upright. The plate 23 is connected by a link 25 to a rod 2G which is moutned to slide in they @rockets 17 and 18 and carries across bar 27 at one end which bears upon the extremities of the rods 12, 13, 14 and 15. A spring 28 surrounds the rod 2o and bears at one end against the 'inner side ot the bracket 18, while at its opposite end the spring has bearing against a collar 29 which is adjustably secured on the rod 26. The spring is confined under tension between the bracket 18 and collar 29, and acts to yieldinglyx maintain the rod 26 and, through the intermediary of the cross bar 27, the rods 12, 13, 14 and 15, in the positions shown in Fig. 3. The separators and their associated parts are supported upon a bracket carried by the machine 'irama and a passage 30 is torinedin said bracket opposite the end of each raceway, as shown in Figs. 1 and Each passage 30 is connected by a y l one of a plurality of tack tubes 32, 33, 34 and 35, herein represented as four in ninber, which are adapted to conduct the separated tacks to openings in the tack block 40,

Fig. 1. The tack tubes are shown as being carried by a bracket which is provided with an opening arranged to receive a sup- .f

porting stud 37, carried rigidly by the machine Vframe, whereby the lbracketmay be slid into position by a lateral movement. A bracket 39, carried rigidlyby the machine trame, has a threaded opening to receive a set screw 38, and the end of said screw has bearing upon a lug p oiecting from the bracket 36 so that when the screw is turned the bracket 3G may be clamped into position.,

short pipe 31V with* properly alined withthe ends of the short pipes 31. The lower ends of the tubes 32, 33, 34 and 35 are connected with a plate 86, which is received in a recess formed in the block 41. Immediately below the plate 86 two passages are .termed in the block 41 opposite the ends of the tubes 32 and 34, which passages unite in a single passage 87, adpated to discharge tacks into a single oritice of the tack block 40 when the latter is in its rear-most position. The block 41 is also provided with two passages opposite the ends ofthe tubes 33 and 35 which unite into a single pasage 88 adapted to discharge tacks into the other receiving orifice of the tack block 40. The block 41 in which these passages 87 and 88 are formed is provided with a threaded shank 88 which passes through a hole in the lower portion of the bracket 36, and a milled nut 42 has an internal thread engaging the threaded shank 88 for thereby holding the block 41 upon the bracket 36. Theblock 41 may be readily removed from the bracket 36 by removing thenut42 'from its threaded shank.

A bracket 43, carried by the machine frame, pivotally supports a hollow shaft 44' having, at its lower end, a fork 45. This fork carries a shaft 46 upon which are pivoted two cams 47 and 48. The cam 47 is connected by a ball and socket jointv to a rod 49, which has its other end connected by a ball and socket joint with an arm 50, formed as an extension of anarm 51 which is pivot-ally supported upon a shaft The arm 51 is connected through a springpressed rod 501 with the usual bunter edge lrest 53 of the machine which slides backwardly and forwardly in a ixed track, and is held yieldingly by the springr in its 'torward position as shown in Fig. 1. lhen the bunter edge rest occupies this position the cam 47 and its associated parts are located as shown in Fig. 6. T ievcam 48 yis connectedby a ball and socket joint to one end of a rod whose opposite end is connected by a ball and socket joint to an arm 55. which is rocked about a vertical pivot bj? connections (i sho-wei to the plaiting mechanism o1 th. machine when this mechanism is thrown into or ont of opera. tion. In Figs. 1, and 6 of the drawings the parts are shown in-the positions which they occupy when the plaiting mechanism is out of operation.

,A rod 57 is mountedfor sliding movement within the hollow shaft 44, and its .ower end projects within the fork 45 and s of snfiicient width to engage either ot the cams "47 and 48. The upper portion of the rod 57 is provided-with a recess which receives a spring 58 confined between a transverse pin 59 carried by the shaft 44.,"a`nd V.the bottom wall of said recess, andv said with the ends of the tubes 32. 33, 34 and 35 spring acts to urgek the rod 57 downwardly V a cam which is provided with a cam roll 71 into yielding engagement with the cams 47 48. The rod 57 is provided with a socket to receive one end of a lever 60, which is tulcrumed at 61 in a supporting sleeve 62 which is mounted to turn upon the shaft 44. A

plunger 63 is urged yieldingly upward' against the inner end of the lever by a spring which is received in a recess in the lower portion of the rod 57. The springs 58, 64 act yieldingly in opposite directions against the inner end of the lever 60, s0 that if the rod is moved in either direction at a time when the lever 60 is not free to turn about its pivot 61 damage to the parts will be avoided.

The lever-60 has an enlarged end 68 which is adapted to coact with the ends of the rods 12, 13, 14 and 15, in a manner to be herein after described, for operating the tack separators. The swiveled support 62 has two rigid projections 65 and 66, as shown in Fig. 2, through which are threaded adjusting screws69 and 70 arranged to bear upon opposite sides oi' an operating lever 67 which is pivoted upon the shaft 44, and is adjustable with reference to the lever 60 by the screws 69, 70. A shaft 73, which `carried in bearings supported by the machine frame and is driven by suitable connections from the main power shaft, carries arranged to engage a-at portion 74 at the end of the lever 67 and acts., 4when shaft 7 3 isy rotated, to impart an oscillating movement to the lever 67. A spring 75, which ex tends between the frame of the machine and the lever 67, acts to hold the flat portion oi the lever in yielding engagement with the cam roll,- and thusv coperates therewith in imparting oscillating movements to the lever. The os'cillatingmovements of the'lever 67 are transmitted through the instrumentality of the projections V65, 66, set screw 69, 70, and support 62 to the separator actuating lever or member 60, which in turn effects reciprocating movementsof those separators which are selected for operation in accordance with the position of the lever 60. It will be observed that, by reason of the springs Q8 and' 75, the'separators will be operated yieldingly in bothl directions, and hence damage toV the parts in the eventl of any partly separated tack becoming jammed between the separators and raceways, will thereby be avoided. j

It is desirable that the timing of the cam 71 and associated partsbe such withv relationto the cycle of operation of the machine that actual separation of the tacks will be effected in the early stages of the cycle vof operation and not, as is customary in hand method lasting machines as heretofore constructed, toward the latter portion of the cycle since by separating the tacks in the same cycle of operation as thatl in which they are inserted in the work any desired change in tack supply can be obtained in the cycle next succeeding the making of the adjustment for producing the change. This subject-matter, however, forms no part or' the present invention as the same is claimed in co-pending application Serial No. 70,169, filed January 4, 1916, which eventuated in United States Letters Patent No. 1,268,357, granted J une 4, 1918, on application of Jerram and Keall.

By reason of the 'tact that the separating devices are located remote from the tack block, and especially where the timing of the separating devices is of the character above indicated, it may be desirable to accelerate the passage of the separated tacks through the tack tubes 3Q, 33, 34, and 35 by a blast of air to be directed into the tubes at the appropriate time. An air pump 76, shown by full lines in Fig. 1 and by dotted lines in Fig. 2 of the drawings,may with advantage be utilized for this purpose, and this pump could be conveniently operated through a bevel gear 77 to be driven by a bevel gear 72 fast on the shaft 73, and a shaft 78 carrying the gear 77 could be pro vided with suitable connections for driving the pump. This feature forms no part of the present invention, but is fully described and claimed in said last mentioned-patent.

Referring now to the operation of the cams 47, 48, it will be observed that when they occupy the position shown in Fig. 6 the rod 57 is not in engagement with the cam 47, but rests upon the high part ot' the cam 48 in which position the enlarged end 68 of the lever 60 is located opposite the ends ot the rods 12 and 13, and upon operation of the machine the lever will, while in this position, effect separation of the long tacks from the raceways 2 and 3. This is. the position that these parts would occupy with the bunter edge rest 53 forward and the plaiting mechanism of the machine inoperative, as when the heel seat of a boot or shoe was being lasted. Because of the thickness of the shoe material at the heel end of the shoe it is desirable at this time to insert two long tacks at each cycle.

During the time that the lasting'` operation is being performed at the toe end of the shoe and the plaiting mechanism is in operation, the rod 54 will be moved through its connections with the plaiting mechanism, eitherV to the right, or to the left, from the position which this rod is shown as occupy ing in Fig. 6, thereby moving cani 48 to the right or to the left, and permitting the rod 57 to be forced by its spring 64 on to a low portion of the cam 48. This will result in raising the outer end of lever 60 so that its enlarged portion 68 will be opposite the end of the rod 12 only, as shown by the broken `lines in Fig. 6, and in4 this position when llO lever 60 is actuated to effect tack separation a single long tack will be separated from the raceway 2 at each cycle.

`When the lasting operation is being performed along the sides, or at the shank of the shoe, the bunter edge rest 53 will be pushed in, as is usual when operating at these portions of a shoe thereby, through the connections described, moving rodV 49 to the left, Fig. 6, and cam 47 to the right to raise the rod 57 and move the lever 60 into the lower position indicated by broken lines, with its enlarged end 68 opposite the rods 14 and 15. When the `lever60 is then operated to elect tack separation two short tacks will be separated from the tacks in the raceways 4 and 5 at each cycleof operation. inasmuch as the cam 47, in this embodiment of the invention, has a greater throw than the high portion of cani .48 the position of lever 60 which is caused by the retracted movement of the bunter edge rest 53 to effect the separation of two short tacks at each cycle will be unaffected by the throwing'into or out of operation of the mechanism to cause plaiting, and hence if it is desired to form plai'ts in the leather when lasting at the shank or sides of a shoe the plaiting mechanism can be caused to operate while two short tacks are being inserted following each pull, and this may bedesirable when lasting these portions of a shoe.

Referring to the modified construction shown in Figs. 7, 8 and 9, the swiveling support 62 is, under this embodiment of the invention, provided with a bearing 79 for a rotatable disk 80 which is provided with an adjusting handle 81 and carries an eccentric stud 61 which Jforms the axis about which the lever 60 is adjusted to co-act with the several rods 12, 13, 14 and 15 connected with the separators. A fulcrum block 82 is pivotally mounted upon the stud 61 and engages a slot 83 formed in the lever 60. It will be seen that by rotation of the handle 81 `the position or' the end of the lever 60 with relation to the ends of the rods 12, 13, 14 and 15 can be manually adjusted so as to effect modifications of the automatic adjustments of the lever which are effected through the action oi the cams 47 and 48. In this embodiment oi the invention the cam 48 is suhstantially of the same construction as the cam 48 in the form of the invention illustrated in Fig. 6; the cam 47 however, which is connected with the bunter edge rest of the machine, is of a somewhat modified construction in that its highest part is so designed as to impart a movement to the rod 57 which will be equal in extent to the .movement imparted to said rod by the high part of the cam 48. c

Referring to Fig. 7 the yparts are shown inthe position which they will occupy withl the bunter edge rest forward and the plaittion. lVith the cams 47 and 48 in this samev position, the disk 8O may be rotated clockwise by its handle 81 to move the stud 61 downwardly into the position shown in Fig. 8 of the drawings. By this movement of the stud 61, the lever` 60will be set with its outer end opposite the rods 14 and 15 in position to effect separation of two short tacks, one from each of the raceways 4 and 5. If the plaiting mechanism is then rendered operative and hence the cam 48 moved in one direction or the other so as to permit the rod 57 to be depressed on to one or the other of the low portions of the cam, the lever 60 will be caused to assume the position indicated by broken lines in Fig. 8 for effecting the separation of a single short tack. If the disk 80 is rotated still farther in the same direction, the stud 61 will be set in the position shown in Fig. 9. The lever 60, however, will still be in position to'efect the separation of two short tacks when the plaiting mechanism is inoperative, but when the plaiting mechanism is rendered operative, the lever 60 will assume the position shown in the dotted lines in Fig. 9 to effect the separation of one long tack. f

It is to be noted that when the stud 61 has` been moved to the inner end of the slot 83, as shown in Fig. 9, the outer end of the lever 60 will be moved a greater distance with a given movement of the inner end of the lever than said lever will be moved when its fulcrum point 61 is adjusted near the outer end of the slot 83, as shown in Figs. 7 and 8, and that the disk 80 is turned through anangle of approximately 18()O in moving the stud 61 'from the position which it is shown as occupying in Fig. 7, to the position shown in Fig. 9.

lWhen the bunter edge rest 53 is moved backward by pressure of the shoe when lasting along the side or shank and the high part of the cam 47 is moved under the rod 57, the lever 60 will be set to eifect, irrespective of whether the plaiting mechanism is operative or inoperative, separation of long tacks from the raceways 2 and 3, when the stud 61 is positioned as shown in Fig. 7, and to eiect separation of short tacks from the raceways 4 and` 5 when the studl is positioned as shown in Fig. 8, or 9.

It is thought that the operation of the machine, and ythe effects of the different adjustments of the tack separating mechanism, have been suiiiciently set forth in connection with the foregoing description of the construction and relative arrangement of the various parts of the machine to be understood without further description.

'While the invention is herein shown and described as embodied in a lasting machine in which preferably loose tacks are driven for securing the lasted shoe materials in position, it Will be obvious that many features of the invention may be employed with advantage in other machines and that it is not essential to the invention what kind of fastenings are handled by the machine.
